Disclosed is a segregating gas arrangement that generally comprises a gas segregation chamber, at least one cooling plate in the gas segregation chamber, and a carbon adsorber in an adsorption gas capturing chamber. The gas segregation chamber has a rim that when resting atop regolith defines a first interior environment. The cooling plates are in the gas segregation chamber, wherein the cooling plates are maintained at a first temperature above 5 K, which is a condensation temperature that higher temperature condensing gases will condense. The adsorption gas capturing chamber defines a second interior environment that is in communication with the first interior environment. The carbon adsorber is in the second interior environment and is maintained at a second temperature below 3 K. The carbon adsorber is configured to capture the low temperature condensing gas.
